摘要： A body to be treated such as a soil or a flying burned ash is introduced into a sealable thermal decomposition furnace (310) and is heated under reduced pressure. A gaseous effluent derived from the body to be treated is treated in a manner wherein formation or resynthesis of dioxin is inhibited. A heating residue of the body to be treated is cooled after it is purged with a gas for displacement which is free of a halogen and has no ability to form an organic halide. By such a treatment, a content of an organic halide remaining in the heating residue of the body to be treated can be reduced to a very low level.

摘要： An apparatus and a method for treating an object material containing a heavy metal and a noxious organic halide, and a method of treating soil. The treating apparatus is provided with an air-tight door (115b) and a retort (115c) as interfaces for taking out to the outside a discharged gaseous material containing an evaporated material from an object material to be treated which is heated under vacuum in an air-tight chamber (103) while maintaining the conditions such as temperature and pressure in the air-tight chamber, the retort (115c) shutting off the air-tight door (115b) in an opened state from the air-tight chamber (103) when the retort is inserted into a first opening (103b) of the air-tight chamber, thus preventing condensation of the discharged gaseous material on the air-tight door.
